<p>1,218,990. Vehicle doors. E. BODE. 19 April, 1968 [21 April, 1967], No. 18600/68. Headings B7B and B7J. In a motor vehicle bodywork, e.g. of a private car or delivery van, an outwardly swingable sliding door leaf 1 is held vertically disposed by two vertically spaced arms 4, 5 each rigidly connected at one end to a shaft 7 rotatably secured in the door aperture frame 6, and each having a roller 8 or 9 at the other end engaging a web 12 of a resepective inverted V-sectioned rail 10 at the inner wall of the door leaf, and a V-shaped guide arm 16 with vertical limbs forming pivot pins is pivoted on one limb 17 at the. approximate centre of a vertical door leaf edge, while the other limb 18 pivotably supports a roller carriage 15 adapted to run on rails 22, 24 disposed externally on the vehicle body. A support arm 29 rigidly secured at the bottom of the other vertical door leaf edge has horizontal and vertical rotation axis rollers 31, 30 respectively, arranged to run on a web 32, of a rail 33 provided in a recess 33a below the lower frame member of the door aperture, and on the base of recess 33a respectively. A main portion of the roller carriage 15 has wheels 23 engaging the rail 24, and a lever arm 19 pivotally secured thereto, at limb 18, has a roller 20 spaced from limb 18 and engaging the inverted V-sectioned rail 22. A roller 20a supported on limb 18 also runs in rail 22. Thus when the door leaf is closed, roller 20 runs into a curved end portion 28 of rail 22. A spring 27 secured at either end to the carriage 15 and the guide arm 16 assists in opening the door. In a second embodiment, Figs. 14-18 (not shown), the central web of a V-sectioned rail is secured against the bodywork, and the guide arm has a roller secured on an arm thereof which runs on a raised portion of the central web. The limbs of the rail have flanged edge portions facing each other and supporting horizontal rotation axis rollers of the roller carriage. Only a vertical roller is provided on the support arm, and is pivotally secured thereon. In a third embodiment, Figs. 19-21 (not shown), one end of the support arm is pivoted to the door leaf and the other end is pivotally secured to a roller carriage frame with rollers running on a straight rail extending across part only of the width of the door aperture frame.</p> |
